    Joint On-theFly Network Coding/Video Quality Adaptation for Real-Time Delivery

    In this paper, the authors introduce a redundancy adaptation algorithm for an on-the-fly erasure network coding scheme called Tetrys in the context of real-time video transmission. The algorithm exploits the relationship between the redundancy ratio used by Tetrys and the gain or loss in encoding bit rate from changing a...

    Two Levels Autonomic Resource Management in Virtualized IaaS

    Virtualized cloud infrastructures are very popular as they allow resource mutualization and therefore cost reduction. For cloud providers, minimizing the number of used resources is one of the main services that such environments must ensure. Cloud customers are also concerned with the minimization of used resources in the cloud since...

    Two-Level Cooperation in Autonomic Cloud Resource Management

    Virtualized cloud infrastructures are becoming very popular as they allow separation of hardware and software management. Infrastructure-as-a-Service (IaaS) is the model providing many advantages to both provider and customer. Minimizing the number of resource (and power consumption) in use is one of the main services that such a cloud model...

    Reliable Multicast Transport of BGP for Geostationary Satellite Networks

    Initially deployed for TV broadcasting, geostationary satellite networks and DVB standards have become mature technologies for IP communications. Also used to interconnect wide IP networks, dynamic IP routing is required in geostationary mesh satellite networks. Nevertheless, terrestrial IP routing protocols are not optimized for satellite networks. Especially, as far as...

    Approaches to Cloud Computing Fault Tolerance

    Fault tolerance in cloud computing platforms and applications is a crucial issue. This issue is especially difficult since cloud computing relies by nature on a complex splitting into many layers. From a technical point of view, most cloud computing platforms exploit virtualization, which implies that they are split into 3...

    Continuous Improvement Through Knowledge-Guided Analysis in Experience Feedback

    Continuous improvement in industrial processes is increasingly a key element of competitiveness for industrial systems. The management of experience feedback in this framework is designed to build, analyze and facilitate the knowledge sharing among problem solving practitioners of an organization in order to improve processes and products achievement. During Problem...

    Opportunistic Secondary Spectrum Sharing Protocols for Primary Implementing an IR Type Hybrid-ARQ Protocol

    In this paper, the authors propose, analyze and compare three different methods for opportunistic spectrum sharing access when the primary user's implements an Incremental Redundancy (IR) type Hybrid Automatic ReQuest (H-ARQ) protocol. The first method consists in allowing the secondary user to communicate only during the first primary transmission round...

    Information Model for Model Driven Safety Requirements Management of Complex Systems

    The aim of this paper is to propose a rigorous and complete design framework for complex system based on System Engineering (SE) principles. The SE standard EIA-632 is used to guide the approach. Within this framework, two aspects are presented. The first one concerns the integration of safety requirements and...

    Defected Ground Structures (DGS) and Uniplanar Compact-Photonic Band Gap (UC-PBG) Structures for Reducing the Size and Enhancing the Out-of-Band Rejection of Microstrip Bandpass Ring Resonator Filters

    In this paper, the authors addresses a modified bandpass ring resonator filter providing compact size, low insertion-loss, wide bandwidth, sharp rejection and suppressed higher order modes. Typically, ring resonator filters suffer from large occupation area and limited out of band rejection. These limitations are tackled in this paper by means...
